It’s a heavyweight, coming in at 3.8 pounds, and it rocks an 11.6-inch LED screen and the Windows Relevant Products/Services 7 OS. It has a videocamera, two stereo speakers, and an integrated microphone for voice chat and other activities.

According to Lenovo Senior VP Liu Jun:

“By fusing the functionality of a notebook with the slate tablet’s rich multi-touch entertainment and mobile Internet experience, U1 provides consumers the freedom to choose the device they prefer for any activity.”

When used as a laptop, the Lenovo U1 actually accesses a second processor within the keyboard for synchronized use. When you remove the 1.6 lb multi-touch tablet you can continue computing in portrait or landscape mode with the ARM CPY running Lenovo’s Skylight OS.

The Ideapad U1 Hybrid can deliver more than 5 hours of 3G web access and should be available this June for $999.
